The complete chloroplast genome of Alniaria alnifolia (Siebold and Zucc.) Rushforth, 2018.

Alniaria alnifolia (Siebold and Zucc.) Rushforth, 2018 (alternative name: Sorbus alnifolia) belongs to the genus Alniaria of the family Rosaceae and is widely distributed in northern China, Korea, and Japan. It is an essential resource used in the construction, pharmaceuticals, and food industries. It is also used to treat various diseases, such as fever, hyperglycemia, rash, asthma, bronchitis, constipation, leprosy, anemia, and other skin ailments. In this study, we sequenced a sample of A. alnifolia and determined its complete chloroplast genome. The chloroplast genome of A. alnifolia has a circular structure with a length of 159,855 bp, which includes a small single-copy region (19,409 bp), a large single-copy region (87,628 bp), and two inverted repeats (26,409 bp). The sequence had 130 genes, including 85 protein-coding genes, eight rRNA genes, and 37 tRNA genes, and the overall GC content was 36.6%. The genes trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC, and ndhA contained one intron; genes clpP and ycf3 contained two introns. Phylogenetic results showed that A. alnifolia had the closest relationship with Sorbus folgneri (MK161058).

The first complete chloroplast genome of Tetradium daniellii (Benn.) T. G. Hartley.

Tetradium daniellii (Benn.) T. G. Hartley is an important medicinal, ornamental, and timber tree species and belongs to genus Tetradium in family of Rutaceae. It is widely distributed in warm temperate deciduous broad-leaved forest areas in northern China, Korean Peninsula and Japan. In this study, we sequenced its sample and determined complete chloroplast genome. The CP genome of T. daniellii has a circle structure with the length 158,446 bp, includes a small single copy region (17, 972 bp), a large single copy (86, 478 bp) and two inverted repeats (26,998 bp). There were 131 genes, which included 86 protein-coding genes, 8 rRNA and 37 tRNA, and overall GC content covered by 38.3%. The gene trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC and ndhA contained an intron; gene clpP, ycf3 contained 2 introns. The phylogenetic result showed that T. daniellii had the closest relationship with Tetradium ruticarpum (NC_052830).

Characterization of the complete chloroplast genome of Syzygium nervosum.

Syzygium nervosum A.Cunn. ex DC (also named as Cleistocalyx operculatus) is a member of genus Syzygium mainly distributed in China, Vietnam and some other tropical countries and belongs the family of Myrtaceae. Syzygium nervosum is a popular medicinal plant, some species of genus Syzygium have been used in folk medicine. In this study, we sequenced the sample of Syzygium nervosum and determined its complete chloroplast genome. The complete chloroplast genome of Syzygium nervosum is 158,979 bp in length, and contained a large single copy (LSC) with 88,099 bp in length, a small single copy (SSC) with 18,756 bp in length and two inverted repeat (IR) regions of 26,062 bp each. It includes 85 protein coding genes, 8 rRNA and 37 tRNA, and 37% overall GC content. Each of trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC and ndhA genes contain an intron, the gene clpP and ycf3 contain 2 introns. The phylogenetic position shows that Syzygium nervosum has the closest relationship with Syzygium aromaticum.

Characterization of the complete chloroplast genome of Dioscorea polystachya Turcz.

Dioscorea polystachya Turcz. is an important Chinese herbal medicine and the raw material of the medicine ingrediente (Chinese yam polysaccharide). It belongs to Dioscorea, which has 60 species and distribute in middle and southeast of China. In this study, we sequenced the sample of D. polystachya based on Jiaozuo, Henan and determined its complete chloroplast genome. The length of cp genome was 152,958 bp, includes two invert repeats (IR) regions of 25,492 bp, a large single-copy (LSC) region of 83,152 bp, and a short single-copy (SSC) region of 18,822 bp. There were 131 genes, which included 85 protein coding genes, 8 rRNA, and 38 tRNA, and overall GC content covered by 37.1%. Each of trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC, and ndhA genes contained an intron, clpP and ycf3 contained 2 introns. The phylogenetic position showed that D. Polystachya had the closest relationship with Dioscorea alata (MG267382) and Dioscorea aspersa (NC039807).
